Application filed June 28, 1909. Serial No. 503,837.

' To all whom it 'may concern:

Fittings; and I do hereby declare the following to be afull, clear, and exact description of the inventionfsuch as will enable' others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters 6r iigures of reference marked thereon, which form a part of this specification.

The subject of my invention is an improved discharge and overflow ittin for tanks and other vessels for containing liquids. v

According to my invention I emplo the discharge conduit in such a manner t at a section of it extends throughout the entire height of the vessel, and. I place within this conduit section a hollow cylinder or tubular member, which-is rotatable about the axis of the conduit section. The walls ot the conduit and cylinder are so perforatedthat the volume of liquid throughout its entire height can .tlow directly into the cylinder and conduit without having to assume an indirect course so that the vessel can be completely emptied with great rapidity.

ing or other purposes and from which thewat'er or other contents is to be discharged. One side of the tank a extending from the top to the bottom thereof is provided with a slot e.

b represents a' conduit cylindrical in outline and one side of which is open and flanged and adapted to be connected to the at Ksnacht, near Zurich, Switzerslotted side of the tank a in any suitable manner, with the edges of the opening in the conduit adjacent to the ed es of the slotted portion of the tank; it cino understood that this conduit connects with a discharge pip? not shown in the drawing.

ithin the conduit b I em loy a cylindrical member d'. adapted to tand to be turned within the same and provided with a slot or opening c extending substantially the fuil length or height of the side of the vessel in which the slot e is provided. The upper end of the cylinder d is preferably provided with a lug g to close the same and with a. handle d y which the cylinder d can be revolved within the conduit b so as to cause-the slot c to register with the slot e;

thereby providing an open communication between the tank a and the dscharge'pipe connected to the conduit b, or tov brlngt e slot c within the walls of the conduit b' to shut ofi this open communication between the tank a and the discharge pipe. ,In the cylinder d adjacent to iits upper end I also prefer to provide an opening indicated at f which is so placed as to be within the walls of the conduit. b when the 'slot c registers with the slot e, and to register with a portion of the slot e whenthe slot c is turned to a position within the walls of the conduit b, so that this opening f acts as an overflow.

I claim as my invention 1. The combination with a vessel adapted to contain a liquid and having a slot extending the entire height of one of its sides, of a conduit having an open portion and adapted to be attached to said vessel so that the open portion of the conduit substantially registers with the said slot in the side of the vessel, and a tubular member fitting within the said conduit and revoluble therein and provided with a slot of substantially the same length as that in the side of said vessel.

2. The combination with a vessel adapted to contain a liquid and having a slot ex- ;tending the entire height of one ot its sides,

registers with the' said slot in the side of the In testimony tiiat I claim the foregoing vessel, and a tubular member fitting -Within :1s my invention, I have signed my name in l0 the said conduit and revoiuble therein and presence of two subscribing Witnesses.
